Research on technical transformation of large dip angle belt conveyor in coal mine main inclined shaft
Whether the main inclined shaft belt conveyor can be timely installed and operate normally during the reconstruction and ex-pansion period of the mine will directly affect the progress of subsequent work.The main problems existing in the main inclined shaft belt conveyor were analyzed,a technical transformation design scheme was put forward,the unloading and driving devices of the large dip angle belt conveyor in main inclined shaft were modified,and a simple and practical reverse device for the belt conveyor was de-signed.At the same time,the anti-rolling device and safety protection device were optimized and modified.Compared to before the sys-tem renovation,the coal delivery time of the main coal transportation system has been advanced by 240 days,ensuring the construction progress of various renovation and expansion projects in the mine and the coal discharge needs in the underground production prepara-tion stage.It has good technical promotion and application prospects.
